Definitions:

Spatial Summation

Summation of the local potentials in which two or more action potentials arrive simultaneously at two or more presynaptic terminals that synapse with a single neuron.

Action Potentials

Electrical impulses that travel along the membrane of nerve cells, allowing them to communicate with other cells.

Presynaptic Terminals

The end points of nerve cells (neurons) where neurotransmitters are released to transmit signals to other neurons or muscles.

IPSP

Inhibitory postsynaptic potential; a synaptic potential that makes a postsynaptic neuron less likely to generate an action potential.
